JOHN MILLER, JR., OF AMESBURY, MASSACHUSETTS, ASSIGNOR TO JLMESBURr BRASS FOUNDBY COMPANY, OEE AMESBUBY, MASSACHUSETTS, A PARTNERSHIP COM- POSED OF ROBERT H. HILLS AND WILLIAM E. BIDDLEl WINDOW REGULATOR FOR WINDOWS OF VEHICLES.

Application illed October 8, 1920. Serial 110.415,59.

To all whom it may concern.:

Be it known that I, JOHN MILLER, Jr., a citizen of the United States, residing at Amesbury, county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Window Regulators for Windows of Vehicles, of which the following is a specification, reference bein had therein to the accompanying drawings.l

MyI Aresent invention relates to mechanism or raising and lowering windows and for locking them in any desired position, and is adapted particularly for use in connection withthe windows of vehicles such as automobiles. One object of vthe in vention is to provide mechanism by which the window can be moved easily by a relatively short movement of an operating handle. Another object of the' invention is to do away with the use of sprockets, chains, counterbalances and straps,all of which are now in common use as parts of window regulators. l

The device embodying my invention is simple in construction and can be enclosed within the window casing so that no part of it, except the handle, is visible from the exterior. The handle is located close to the window pane and within the line of the upholstery of the automobile so that it does Anot project to an inconvenientA extent. This does awaywith one of the great objections to the ordinary window regulator as at present commonly constructed, namely, that the revolving operating handle projects inwardly and catches on the clothes of the persons using the vehicle so that pockets and sleeves are frequently torn. The arrangement described by which the handle does not project beyond the line of the upholstery, also renders the vehicle safer for the occupants, since there is less danger of injury if the occupants are thrown violently against the side of the car.

The device embodying my invention, besides bein much more satisfactory to use in the vehicle, is simple and inexpensive to manufacture and contains no parts which require adjustment or replacement after the device has once been installed.

The invention will be fully 'understood from the following description when taken in connection with the accompanying drawings, and the novel features thereof will be pointed out and clearly deined in the claims at the close of this specification.

In the drawings, Fig. 1 is a side elevation of the device embodying my invention as applied to the window of a limousine.

Fig. 2'is an enlarged section taken on line 2 2 of Fig. 1.

Fig. 3 is a detail of the elbow member and operating handle.

Fig. 4 is an edge view of the elbow memticularly to Figures 1 to 4, at A is shown the window casing, at B the sliding sash, at C the pane of glass and at, D the line of the upholstery.. It will be understood that the window casing is hollow and that the window drops down into the interior of the window casing when it is desired to open the window.

Underneath and at one side of the lower edge of the sash B is located an elbow lever 11 preferably of the form shown in Figures 1, 3 and 4. This lever is pivoted at 12 to a bracket 4 secured to the window lcasing and has a plurality of arms. One arm a is provided with a roll or spool 13 which is movable between the lower edge of the sash and a track; member 14 secured to the lower edge of the sash, so that the spool will exert a positive action on the sash to move it either up or down. This arrangement makes it possible to pull the window down by the regulator in case it sticks suiciently to resist the force of gravity and also prevents accidental discon- 'nection of the parts. Another arm b of the elbow member 11 extends downwardly from the. pivot 12 and is provided with a series of notches c one of which is engaged by a spring 15 secured at 16 to the window casing A. Several notches are provided to make it possible to vary the leverage and consequently the force by which'the sprlng exerts on the window sash and forms means for adjusting the regulator according to the dow, the handle 17 is pushed inwardl weight of the sash and the amount of friction between the sash and the window casing. The arm b is offset as shown in Figures 2 and 1 so that it and the spring 15 lie between the outside of the sash and the corresponding interior face of the window casing. This construction permits the elbow member to be pivoted close to the outer wall of the window casing, and the sash to slide past the spring, thereby permitting greater range of movement for the sash. Another arm of the elbow member 11 is U-shaped, one leg d of the U lying on the outer side of the sash and the other leg e lying on the inside of the sash, the two being connected by a portion f which passes around the bottom edge of the sash. The leg e of the U-shaped arm extends above the garnish rail 18 of the window casing and is ro',` vided on its upper end with a handle 17) by which the window regulator can easily be moved.

On the inside of the inner wall of the window casing and disposed substantially parallel to the path of movement of the leg or handle arm @,is placed a sector 19 which is entirely concealed from view. This sector is formed on its circumferential edge with notches which are engaged by a catch or lug 2O which projects laterally from the handle arm e and is normally in engagement with one of the notches in the notched sector 19. To disengage the catch from the notched sector, the handle is pushed laterally inwardly toward the pane of glass, its length and material being such as to permit it to spring enough to accomplish this result. v

The operation of my device is as follows :--`When. it is desired to lower the winsuiiiciently to disengage the catch 20 from the notch in the sector 19 and the handle is moved to the left as indicated by the arrow in Figure 1. This swings the elbow lever 11 about its pivot 12 extending the spring 15 and allowing the sash to slide down or pulling the sash down if it sticks. When the window has reached the desired position, the handle is released and it springs back, causing the catch 20 to engage the appropriate notch, thereby locking the window in place so that it can be moved neither up nor down vwithout disengag'ing the catch from the notched sector. When it is desired to raise the window, the handle 17 is again pushed in toward the pane and moved to the right. During this movement, the spring 15 as sists in overcoming the wei ht of the window, and the window can e moved with very little effort.

Referring now to Figures 5 and 6, there is shown in these gures a window regulator intended particularly for use to operate windows in the doors of automobiles, which windows should have a considerably greater range of movement than the quarter windows of a limousine. In this figure the window or door casing is shown at F, the sash at G, and-the glass at H. An elbow member 25 is pivoted at 26 to a bracket 27 which is secured to the outer wall of the window casing` or door. One end of this lever 25 carries a roll 28 operating in a slot 29 formed between the guide 30 and the lower edge of the sash Gr. The other end of the elbow member 25 is notched as shown at g, and a-spring 31 is connected thereto and to the bottom of the interior of the window casing or door as shown at 32. The spring lies in a position slightly inclined from the horizontal and serves to counterbalance the weight of the sash and pane. At 33 is shown a handle lever pivoted at 34 to a lug 35 secured to the bottom of the window casing or door. The handle lever 33 extends upward close to the inner wall of the frame and terminates at its upper end in a knob or handle 37. At 38 is shown a concealed notched sector secured to the inside of the window casing. The handle lever 33 normally rests against the sector with a catch 39 engaging one of the notches in the sector. The catch may be released by pushing the handle 37 toward the window pane, this movement being permitted by the resiliency of the handle lever 33. The handle lever 33 acts on the elbow member 25 through a link 40 connected at 41 to the elbow member and at 42 to the handle lever.

From the foregoing it will be seen that movement to the left, as indicated by the arrow in Figure 5, moves the long arm of the elbow lever 25 downward and opens the window, while movement to the right moves y the long arm upward and raises the window.

Tt will also be seen that the action of this embodiment of'my invention is substantialy the same as that shown in Figure 1, since the handle 37 acts through a link on the counter-balanced elbow lever to raise and lower the Window by contact of the end of the elbow lever with the lower edge of the sash.
